此成员是显式接口成员实现。This member is an explicit interface member implementation. 它只能在 Boolean 实例被强制转换为 IConvertible 接口时使用。It can be used only when the Boolean instance is cast to an IConvertible interface. 建议的替代项是调用 Convert.ToSingle(Boolean) 方法。The recommended alternative is to call the Convert.ToSingle(Boolean) method.
